4 Claims.

One of the objects of the instant invention is to provide a construction of hardware applicable to existing types of double hun window sashes. for converting such window sashes into swingable reversible sash windows for rendering both sides of the glass panes accessible from a convenient in erior position for cleaning and facilitating adjustment of the swinging sashes for ventiation purposes where each cash is pivoted adjacent the upper and lower portions of the window frame.

Another object of my invention is to provide a construction of hardware for converting double hung window sashes into swinging reversible sash windows where the two sashes are pivotally mounted on horizontal axes immediately adjacent the upper and lower limits of the window frame, facilitating the tilting of the sashes with respect to the top and bottom of the window frame.

Still another object of my invention is to provide an improved structural arrangement of pivot means for safety reversible windows by which sash windows pivoted adjacent the upper and lower portions of the window frame may be adjusted to a selected angular position and maintained in the adjusted angular position, providing access to either side of the glass panes of the sash.

Still another object of my invention is to provide a novel construction of weather stripping for swingin sash windows wherein sash strips individual to each window sash carry weather stripping members which are projectable and retractable from the sash strips into the edges of the window sashes when the window sashes are moved to closed positions vertically slidable as a double hung window within a window frame.

Still another object of my invention is to provide an improved mechanism for controllin the position of weather stripping projectable and retractable with respect to opposite sides of window sashes of the double hung convertible type.

A still further object of my invention is to provide an arrangement of weather stripping members for composite swingable and vertically movable window sashes of the double hung type in which novel control means are'provided adjacent the top of each window sash for projecting or retracting the weather stripping members from sash strips located in the stiles of the window frame with respect to the opposite edges of the window sashes for providing a weathertight connection between the window frame and the sashes when the sashes function as a double hung window, while facilitating the conversion of the sashes to pivotally mounted units swingable from positions adjacent the top and bottom of the window frame.

Still another object of my invention is to provide a composite double hung vertically movable and angularly adjustable window sash construction which may be installed in association with storm sash equipped window frames where the storm sashes normally offer obstruction to the swinging movement of the window sashes, but wherein the construction of my invention per.- mits angular displacement of'the window sashes interiorly with respect to the window frame without obstruction to a storm window mounted exteriorfy of the window frame.

Other and further objects of my invention reside in the construction and arrangement of double hung window sashes converted for reversible Swinging movement, as set forth in the specification hereinafter following by reference to the accompanying drawings, in which;

My invention is a substantial improvement over the safety reversible window constructions referred to in my hereinbefore cited Letters Patents and application for Letters Patent, in that I provide hardware for converting double hung vertically slidable window sashes into swingable sash windows movable about'axes adjacent the top andbottom of the window frame. In my prior developments the sash windows have been pivoted along a horizontal axis centrally thereof so that each window sash is swingable both exteriorly and interiorly of the window frame. This is a substantial disadvantage where it is desired to utilize the advantages of the swingable sashes in installations where exterior storm windows and screens are mounted. By the arrangement set forth in my invention the sashes are each pivotally mounted for interior swinging movement and without exterior swinging movement, so that the sashes project interiorly through the frame but not exteriorly thereof throughout all positions of adjustment. Accordingly, storm windows with removable sashes and replaceable screens may be installed. Inasmuch as there is no exterior movement of the sashes in accordance with the arrangement of my invention, no interference is offered to the installed storm window or associated window screens therein.

The double hung window sashes, after removal from the stiles of the window frame, are trimmed at opposite edges thereof and a sash strip applied to each edge thereof. The sash strips are vertically slidable in the stiles of the window frame. These sash strips each carry special hardware fittings each constituting an annular trackway on the sash strips for coaction' with hardware members mounted on the opposite edges of the window sashes and having spaced cam members operative to enter the trackway in the hardware fitting carried by each sash strip. The hardware fitting carried by the 'sash strip is: slotted centrally and vertically with respect to the sash strip, the slots being disposed in oppositely spaced positions of the circular trackway whereby the spaced cam members carried by opposite edges of the sashes are displaced transversely as the sashes are subjected to a swinging movement out of alignment with" the sash strips. As the window sashes equipped with the hardware of my invention are displaced anigularly, the spaced cam members are thrust away from the diametrically'opposite slot portions of the hardware carried-J by the sash strips and revolve within the annular'trackway of the hardware carried by the sash strip. The yieldability of the window frame construction is sufficient to permit this slight transverse displacement and allow the window sashes to be moved at an angle with respect to thesash strips and projecting interiorly from the window frame without interference to obstruction offered by the storm window or associated screen mounted therein.

The sash strips in my present invention also carry weather stripping members. Each weather stripping member'is mounted in a longitudinally extending slot in the sash strip, and I provide means adjacent the upper end of each sash strip for projecting and retracting the weather strippingmember with respect to the sash strip. Coacting with the projectable and retractable weather stripping member, I provide grooves in each edge of the c'oacting'window sash. When these grooves are aligned with the weather stripping members carried by the sash strips, the weather stripping members may be projected from the sash strips into the edges of the sash.

- I provide various forms of manipulating means for projecting and retracting the weather stripping members. Also, I provide various arrangements of weather stripping members which may be projected or retracted from the sash strips into opposite edges of the sashes. Thus, weathertight joints are established and maintained between the sashes and the'sash strips when the window sashes are movedtopositions aligned with the sash strips and vertically movable as a double hung window in the window stiles.

Referring to the drawings in more detail, I have shown the hardware ofmy invention for converting double hung windows intomodern swinging sash windows wherein reference character I designates the frame of a double hung window having vertically arranged stiles 2 and 3. The window sashes i and 5 are normally slidable in the vertically arranged stiles 2 and 3. In converting the double hung window to a swinging sash window in accordance with my invention, each window sash is trimmed on each edge thereof for receiving a sash strip 6 and 1 coacting with window sash 5, and sash strips 8 and 9 coacting with window sash 4. The sash strips are vertically adjustable in the window stiles 2 and 3. The pairs of sash strips for each sash are controlled in vertical adjustment by means of sash cords and sash weights associated therewith. For example, the window sash 4 is provided with sash strips 8 and 9 which connect through sash cords Ill and I I to sash weights l2 and I3. When sash strips 8 and 9 and the associated window sash 4 are in their lowermost position the weights I2 and I3 are in the positions illustrated in Fig. 1. Similarly, when window sash 5 is in its normal position the sash strips 6 and 1 connect through sash cords Ma and |5a to sash weights l4 and I5 operative within the window frame casing. The respective sash strips 6, I, 8 and 9 connect withthe coacting cords for effecting a controlled and balanced vertical movement of the sash strips and the window sashes associated therewith.

The window sashes are each provided at the cutaway edge portions thereof with special hardware fittings illustrated more clearly in Figs. 14,

'15,and 16, and in which plate I 6 is mounted flush with the edge of the sash. The plate l6 of each hardware fitting is set into the edge of the sash member 5 adjacent the extreme upper transverse edge thereof designated at I9. The plate I6 carries a pair of spaced cam members represented at H and I8. Correspondingly, hardware plates l6 are mounted on opposite edges of window sash 4 immediately adjacent the extreme lower horizontal edge thereof designated at 20. Each of the sash strips carry coacting plates 2| transversely aligned with the plates I6 in the sashes. The plates 2| each include an annular trackway 22 into which the cam members I! and I8 are adapted to project when the sashes are tilted, as explained hereinafter. The plates 2| are each slotted as represented at Ma and 2| 1; in a position centrally with respect to the sash strip, and provide recesses into which the cam members I1 and [8 on plates [6 extend when the sash is in vertical alignment with the sash strips. As the window sashes 4 and 5 are turned, the cam members I! and [8 of plate l6 move out of the recesses Zia and 2Ib and revolve throughannular trackway 22 as a guide for controlling the angular shifting of the window sashes. The annular surface of trackway 22 is milled to provide a friction bearing surface for the ends of cam members I1 and [8 so that the sashes 4 and 5 remain in the angular positions to which they are tilted for cleaning or for ventilating purposes.

The positions of the coacting plates IS on the window sashes, and the coacting plates 2! on the sash strips, are selected so that sash 5 may revolve around a transverse axis designated at 23, while window sash 4 may revolve around a transverse axis 24, each of which are designated by dash-dot lines in Fig. 1. These transverse axes 23 and 24 are disposed in such close proximity to the upper ends of the sash strips 6 and 1 and the lower ends of the sash strips 8 and 9 that the window sashes extend outwardly in a very restricted path, as represented moreparticularly in Figs. 2Qand 5 wherein the window sashes 4 and 5 are angularly adjustable without offering any obstruction or interference to the storm window 25 set or mounted exteriorly of the window frame I.

6 The storm window 25 is of conventional type adapted to interchangeably receive a screen for summer installation, or a glass window for winter installation. In either case the outward projection of the window sashes 4 and 5 is substanticularly with the composite vertical and angular movement which is possible in the arrangementof my invention, in that both sides of the window sashes become available at the interior of the installation for washing and cleaning without the necessity of stretching around the window sash or working exteriorly of the window sash, and proper ventilation may be secured by the desired angular setting of the sashesi The manner of adapting weather stripping members to the improved composite sliding and swinging window sashes of my inventionis a particular feature of my invention. In my improved arrangement the weather stripping member is not carried by the window sashes, but on the contrary is mounted in each sash strip. The construction is more clearly illustrated in Figs. '7 and 8from which it will be seen that the sash strip 6, for example, is longitudinally slotted at 6a through which the weather stripping member 26 extends. The weather stripping member '26 .carr'ies'a felt edging 21 which is adapted to be projected with the weather stripping member 26 .into the groove 28 formed in the edge of the members are represented as extending from the tops of the sash strips at 39, 3|, 32 and 33. The controlling means are shown more clearly in Figs. 6, 7and 8 and include a manually liftable element34 secured to the weather stripping member 26 operating in slot 6a in sash strip 6.

y lifting the manually liftable element 34 the weather stripping member 25 is projected into the aligned groove 28. This is accomplished by the arrangement of inclined cam slots 35 and 36 formed in the weather stripping member 25 and which ride upon pins 31 and 38 extending through the sash strip 6. Downward movement of manually liftable element 34 efiects a retraction "of weather stripping member 26 which returns to and is housed Within the coacting groove 6a in the sash strip 6.

When the manually liftable element 34 is moved to its extreme upward position the end of liftable element is angularly revolved to engage an abutment stop 39 on sash strip 6, thereby maintaining the weather stripping member 26 in projected position. The abutment stops 39 extend up wardly from the upper ends of the sash strips and have a width approximately equal to one-half thewidthof the sash strips. The stops 39 constitute raised abutments with respect to the tops of the sash strips and the manually liftable elemnts 34 are linearly-movable adjacent one side of the. raised abutments 39 and are oriented so that portions: of; the liftable elements 34 may be; confined by the tops of the raised abutments. This movement is made possible by the fact that liftable element 314 is connected to the coactin sash strip through a swivel connection designated at" 34a.

The manually liftableelements 34 of the; control means. 32 and 33 for the lower sash are provision of pocket recesses Ml and 4| in the upper portion of 'the window framev L When the window is in closed position, control means 30 and 3! are housed in these recesses. The upper sash 5 is lowered, however, when it is desired to actuate the manually liftable elements 34 for controlling the position of the: weather stripping members respect to the edges of sash 5.

In Figs. 14-16 I have illustrated in detail the construction'of the hardware fitting which is attachedto opposite edges of the sashes. It will be observed that the plate. i6 is substantially H- shaped with cam members H and i8 projecting transversely at spaced positions in alignment with the trackway 22' of the hardware fitting shown in Figs. 17-20.

The hardware fitting illustrated in Figs. I7-20 is also of H-shape contour in that the plate 2| is slotted in central vertical positions indicated at 2m and 2 lb leaving a central circular portion within the annular trackway 22. As heretofore noted the annular trackway 22 i milled or roughened to provide friction grip surface against which the cam members I! and i8 rub in the course of angular movement of the sashes enabling the sashes to be maintained in the positions to which they are moved. It is to be emphasized that the improved construction of my invention enables the sashes and 5 to be angularly adjusted to positions extending interiorly of the building structure as illustrated in dotted lines in Fig. 2 and'in full lines in Figs. 5 and 12 without interfering with the composition storm window or screen 2 5, thereby rendering the structure of my invention highly practicable and convenient for use.

I realize that various modifications of my invention may be made and I desire that it be understood that no limitations upon my invention are intended other than may be imposed by the scope of the appended claims.
